Enum Error 

#[non_exhaustive]
pub enum Error {
    Config(String),
    Parse {
        what: String,
        index: usize,
        reason: String,
    },
    Simulation(String),
    Baseline(String),
    BackendUnimplemented(String),
    Io(Error),
    Toml(String),
    Json(Error),
}

All error conditions the core can surface.

Variants map onto the documented CLI exit codes (see the cu-profiler-cli crate) so the boundary layer can translate an Error into a stable code.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Config(String)

The configuration file was missing, malformed, or semantically invalid.

Parse

A Solana log line could not be parsed. Carries enough context to locate and explain the failure.

Fields

what: String

What the parser was trying to read (e.g. "compute-unit line").

index: usize

Zero-based index of the offending line within the log stream.

reason: String

Why parsing failed, in plain language.

Simulation(String)

A simulation backend failed to execute a scenario.

Baseline(String)

A baseline could not be read, written, or compared.

BackendUnimplemented(String)

A backend exists as an interface but is not implemented in this build.

Io(Error)

An underlying I/O failure.

Toml(String)

A TOML (de)serialization failure, kept as a string so the error type stays independent of the toml error representation.

Json(Error)

A JSON (de)serialization failure.

Implementations

impl Error

pub fn parse(what: impl Display, index: usize, reason: impl Display) -> Self

Build a Error::Parse without repeating the field names at call sites.

Trait Implementations

impl Debug for Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Error

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(e: Error) -> Self

Converts to this type from the input type.
